With such a component it is possible to build a rail securing arrangement with a system, in which the forces are dispersed by a shoulder present at or in the solid substrate, whereby a cut-out is formed into the underside, the dimensions of which are adapted to the shoulder such that, in the installation position, the shoulder engages freely into the cut-out, and in that a reinforcement rib is formed at a roof surface opposite an opening of the cut-out, which projects in the direction of the opening over a height which is less than the cut-out.

Abstract: A device for positional securing and guiding of rails for railway tracks for trains, in particular high-speed trains, includes guide plates. In general, rails are laid directly or indirectly by intermediate assembly of intermediate plates to fixed concrete track beds and guide plates, against which the rail base and possibly intermediate plates lie laterally. Guide plates are embedded on or in the concrete track beds, wherein the guide plates are fabricated of high-strength, form-stable material, preferably reinforced plastic, such as for example glass-fiber reinforced plastic, in particular polyamide. The device according to the invention allows to create guide plates which are overall more wear resistant. Wear resistance is achieved in that the guide plate within the surface area, on which the rail base rests, has an insert or areas provided with inserts, the insert being fabricated of slippable, low-abrasion or friction-resistant, low-wear or wear-resistant and flexibly resilient material.

Abstract: A system for fastening a rail on a substrate includes a base plate, molded into which is a central portion, the width of which is adapted to the width of the rail foot of the rail to be fastened, with at least one fastening element for connecting the base plate to the substrate. The at least one tensioning element is provided for holding down the rail on the base plate. The system provides a fastening system allowing fastening of rails that satisfies modern requirements with the additional benefit of low production costs and simple assembly, while maintaining the basic configuration of the base plate provided and using simple means.

Abstract: A device for securing railway rails (12) on a solid track includes a standard concrete sleeper (16) used for the ballast track. Each of the rails (12) is guided between two angle guide plates (30) and urged by a tensible clamp (34) against the concrete sleeper (16). A resilient intermediate plate (52) is disposed between the rail flange (14) and the standard concrete sleeper (16) and, at their ends remote from the rail (12), the angle guide plates (30) include a first (24) and a second surface (28), the first surface (24) being inclined obliquely to the vertical in the mounted position and abutting a correspondingly shaped sloping surface (44) of the standard concrete sleeper (16). The second surface (28) is aligned substantially vertically and rises over the top of the standard concrete sleeper (16).

Abstract: The invention concerns a rail fastener on concrete ties (4) or the like including resilient tension clamps (6) of steel rods in the form of a W and angled guide plates (3) for the rail base (1a). This so-called HM rail fastener is inventively improved by a special shaping of the tension clamp and angled guide plate, to simplify the securing of the rail on the concrete ties, in that the rotation of the elastic strainers which was previously necessary in HM construction when passing from the preassembly to the assembly position is omitted. This is achieved in that the angled guide plate (3), which is provided with a rib (3a) extending longitudinally to the rail foot for abutment on the rail foot (1a), contains in this rib special recesses (3b) for the reception and retention of the free ends of the tension clamp in the preassembly position.

Abstract: A device for attaching a rail to a bearing element (tie) (3) and comprising an elastic intermediate plate (34) and on top of this a rigid pressure distribution plate (35) which is arranged between the base (2) of the rail (1) and the tie (3); guide plates (10, 11) are attached to the tie (3) to provide lateral guidance of the base of the rail (2) and clamps (38) act on the base of the rail (2) and clamp the rail (1) to the tie (3). The elastic intermediate plate (34) projecting on both sides beneath the base (2) of the rail (1) extends on each side into a recess (16, 17) formed by the guide plate (10, 11). As a result, the elastic intermediate plate (34) can provide adequate resistance to the horizontal forces so that tilting of the rail is prevented. At the same time, the major forces of the clamps (38) are transmitted via the guide plates (10, 11) directly to the tie (3) so that non-uniform compression of the elastic intermediate plate (34) cannot occur during assembly and thus rail cant errors are avoided.

Abstract: The invention describes a clamp for rails that is produced from resilient steel bar with multiple bends. The first section (11) of the rail clamp (9, 10) is essentially horizontally arranged, while the last section (14) rests on the rail flange (5). The second section (12) curves upwards in the vertical plane that passes through the first section (11). The remaining sections of the clamp lie all on the side of the first section that faces the rail. The fastening arrangement comprises an anchoring part (20) where the supporting surface (23) for a supporting section of the clamp (9, 10) is located essentially vertically above the locating hole (24) of the clamp (9, 10). That produces a relatively short clamp requiring a minimum of material.

Abstract: Anchor for a railway tie embedded in ballast. In order to further simplify the installation of such an anchor, the clamp is constructed in two or more parts. With an anchor construction having a clamp gripping the tie on both sides, the clamp parts are constructed of approximately the same size in order to form clamp halves, the connection is formed as a pivot arrangement and in the region of the connection position a tightening means is provided for producing a tightening force clamping the clamp halves on the tie.

Abstract: For achieving improved securing effect in use with oil or wax coated contact surfaces, a self-locking resilient or non-resilient element, such as a spring-ring or a washer, has wall-like protrusions extending on each major surface from the inner to the outer boundary, and recesses lying therebetween, the protrusions each having a plateau-like upper surface which, viewed in cross-section along the peripheral direction of the element, is curved concavely in order to form edges lying in the region of the plateau boundaries, the edges being formed as scraping edges. The wall-like protrusions extend radially in a zig-zag manner from the inner boundary to the outer boundary of each major surface, and each of the recesses lying between the protrusions forms a zig-zag-shaped continuous channel, open in the region of the inner and outer boundaries in order to achieve a drainage effect.

Abstract: The invention relates to a rail securing arrangement, which has the following features. It comprises metal plates, each of which lies with its flat lower surface on the sleeper, and on whose upper surface two ribs are formed which extend in the longitudinal direction of the rail, and between which the foot of the sleeper lies on a bearing surface. On both sides of the rail in the region of the respective ribs, each plate has moreover at least one through-hole, with which a respective through-hole in the sleeper is aligned. Corresponding screws are each introduced with their lower ends into the respective through-holes of the plate and engage with a hook-like bend beneath the lower surface of the plate. Each screw is provided at its upper end with a thread onto which a respective nut is screwed. Furthermore, the securing arrangement comprises plate-like securing elements which are each bent to form a double-armed angle member.

Abstract: An arrangement for fastening rails to sleepers includes guide plates (10) disposed to the sides of each rail and elastic clips (20), which may be pressed onto the respective guide plate (10) and onto the foot of the rail by means of bolts (30) anchored in the sleepers, the guide plates (10) having on their upper side in the installed position a rib (13) extending parallel to the rail, on which a part (21) of the elastic clip may be brought to seat as a boundary for the stress path.In order that the guide plates (10), when made also from plastics, may safely carry without damage the forces exercised by the clips (20), even when there has been an excessive torque on the bolts (30), each rib (13) of the guide plate (10) has a reinforcement (14) in the seating region of the clip (20).
